Quote from : Jitterbug Perfume Book

In addition, Dr. Dannyboy has suggested a fifth element: positive thinking. Pointing out that their breathing, bathing, dining and screwing brought Alobar and Kudra much physical pleasure, and that an organism steeped in pleasure is an organism disposed to continue, he has said that the will to live cannot be overestimated as a stimulant to longevity. Indeed Dr. Dannyboy goes so far as to claim that ninety percent of all deaths are suicides. Persons, says Wiggs, who lack curiosity about life, who find minimal joy in existence, are all too willing, subconsciously, to cooperate with- and attract- disease, accident and violence.
